I wired the supply rails backwards :-[ I've got 5v going to the LCD and 12v going to the everything else. Ooooops! I don't think I've cooked anything, but, by the same token... ya know, guys, I really don't think it's going to work out very well, wired like that...

I know exactly how it happened, too... to get the power socket to fit, I had to stick it in upside down.

Time to get out the iron :-\

You aren't the first, only the most recent...  And maybe not even that!

Try a Blinky example on your Arduino before you bother with the real project.

Blinking an LED with a microcontroller is something I do when I need a nap, ugh :=\

I'd rather use a 555 for that, anyways... I'm good with hardware that DOESN'T need programming, lol.

Thanks also for the o-scope tutorial, I'll pull it out after I fix the power supply issue. Gimme... 30min or so? I'm slow and the wiring is tight there.
starhawk:
Power's fixed. Alas, the SD card is toast. I'm going to see if I have another really tiny one...

EDITNESS: A friend is bringing me a new card in about an hour... testing will resume once the card is formatted and programmed.

And if your project still doesn't work, how do you know the CPU is doing anything rational?  It's a rare project that works right out of the gate.

Think about the number of thing that have to work perfectly to get that LED blinking?

This is why you always check power supply voltages when powering anything up for the first time!
